Magnetic field study of exciton nonradiative broadening excitation spectra in GaAs/AlGaAs quantum wells
M. A. Chukeev, A. S. Kurdyubov, I. I. Ryzhov +4
Exciton excited states in the quantum well are studied via their effect on the nonradiative broadening of the ground exciton resonance. Dependence of the nonradiative broadening of…
Unveiling the electron-nuclear spin dynamics in an n-doped InGaAs epilayer by spin noise spectroscopy
C. Rittmann, M. Yu. Petrov, A. N. Kamenskii +6
We discuss the implications of a small indium content (3%) in a GaAs epilayer on the electron- and nuclear-spin relaxation due to enhanced quadrupolar effects induced by the strain…
Inversion of Zeeman splitting of exciton states in InGaAs quantum wells
P. S. Grigoryev, O. A. Yugov, S. A. Eliseev +5
Zeeman splitting of quantum-confined states of excitons in InGaAs quantum wells (QWs) is experimentally found to depend strongly on quantization energy. Moreover, it changes sign w…
Effect of irradiation by He+ and Ga+ ions on 2D-exciton susceptibility of the InGaAs/GaAs quantum-well structures
Yu. V. Kapitonov, P. Yu. Shapochkin, Yu. V. Petrov +5
The effect of irradiation by 30-keV Ga+ and 35-keV He+ ions (in relatively small doses) on the excitonic reflectivity spectra of single InGaAs/GaAs quantum-well structures is studi…
Nontrivial relaxation dynamics of excitons in high-quality InGaAs/GaAs quantum wells
A. V. Trifonov, S. N. Korotan, A. S. Kurdyubov +8
Photoluminescence (PL) and reflectivity spectra of a high-quality InGaAs/GaAs quantum well structure reveal a series of ultra-narrow peaks attributed to the quantum confined excito…
Extremely low inhomogeneous broadening of exciton lines in shallow (In,Ga)As/GaAs quantum wells
S. V. Poltavtsev, Yu. P. Efimov, Yu. K. Dolgikh +3
We study radiative linewidth of exciton resonance in shallow InGaAs/GaAs single quantum wells as a function of indium concentration in the range and wel…
